I SHEET MATERIAL AND METHOD OF INCORPORATING THE SAME IN A COVERING STRUCTURE.

v Application filed April 23, 1926. Serial No. 104,127.

This invention relates to sheet material suitable, for example, to be interposed between a floor and rubber or other floor-cow ering material thereon.

5 Heretofore felt sheets without a binder or impregnation have been employed as an under layer for rubber and for linoleum flooring and the felt sheets have been secured to the rubber or linoleum flooring and to the 1 door by the use of adhesives containing water as applied and of such character as to result in damage to the structure by the ingress 0t water or moisture after the installation has been completed. ll also have employed a floor-covering comprising a sheet of rubber secured to a backing sheet of bituminous material, as described in my co-pending application Serial No. 104,126, filed April 23, 1926, which has permitted the use of desirable adhesives which contain quickdrying solvents, such as the usual waterproof linoleum cements, but the product there described for the best results requires that the rubber sheets be vulcanized to their il backing sheets, which cannot conveniently be done exceptwith equipment which is not readily available except at the rubber factory, and uneven floors frequentl require a sub-layer of such thickness and character to that it cannot be conveniently and economically attached to-the rubber sheet at the factory and distributed therewith.

My chief objects are to provide sheet material adapted tobe conveniently secured to a at floor or the like and to have a sheet of rubber conveniently secured to its opposite face without vu canization, as in the laying of door covering material. A further object is to provide a floor-covering structure or the at like of which allof the parts advantageously mtg be assembled at the lace of use. if the accompanying rawings:

Fig. 1 is a perspectivewiew of my improved sheet material in its preferred form. Fig. 2 is a section of the same,

Fig. 3. is a section of a ortion of afioor and a floor covering inclu ing my improved sheet aterial thereon.

Re erring to the drawings, the im roved sheet material comprises a sheet of elt 10,

specific structure or adapted tdresi'st the softening and loosening action of water after it has dried.

llo an appreciable depth from the opposite face the felt sheet i0. is free of such binder or impregnation, as shown at 13, so that it conveniently and effectively may be secured to an overlying sheet of rubber M by the usual water-soluble adhesive.

The felt sheet is secured to the rubber sheet 14 and to the lloor 12 by respective adhesives of the characteristics described, with the result that the floor covering, by reason of the binder inthe region 11 and the waterresistin adhesive securing it to the door, is adapts to prevent water or moisture from rising into-it from the floor, and the unimpregnated condition of the upper portion of the felt sheet permits a com aratively rapid evaporation of both of the so vents employed II in the two different cements.

I do not wholly limit In till claims to the proce ure herein described, as my invention is susceptible of modification and of diiferent applications within its scope.

I claim: r

1. In combination with a sup ort such as a floor, a facing sheet, a sheet 0 fibrous material between the two, the said sheet having its surface portion ad acent the su port impregnated with a water-proof bin er and a 'zone nearer its opposite face free of such binder, and a water-proof adhesive securing the sheet to the support.

2. A combination as defined in claim 1 in which the facing sheet is secured to the sheet of fibrous material.

3. The method of making and mounting a coverin which comprises producin a sheet of brous material with the sur ace portion of only one side im regnated with a water-proof binder, and t ereafter securingthe impregnated surface thereof to a surface to be covered by means of a water- 100 proof cement, and securing a. facing sheet to pregnated surface thereof to a surface to be the opposite face of the sheet of fibrous macovered, by means of a water-proof cement, 10 teria and securing a facing sheet to the opposite 4. The method of making and mounting a surface of the sheet of fibrous material by 5 covering which comprises producing a sheet means of a Water-soluble adhesive.

of fibrous material with the surface portion In Witness whereof I have hereunto set my of onl one side impregnated with a, waterhand this 16th day of April, 1926. proof hinder, and thereafter securing the im- TOD J. MELL.
